Abstract
Description
Die Erfindung betrifft oxidische Partikelmischungen (Emailmischungen), die für die Herstellung von selbstreinigenden Emailschichten auf Stahl geeignet sind, ein Ver fahren zu ihrer Herstellung sowie ihre Verwendung.The invention relates to oxidic particle mixtures (enamel mixtures) for Manufacture of self-cleaning enamel layers on steel are suitable, a Ver drive to their manufacture as well as their use.
Selbstreinigende Emails sind seit längerem bekannt und in diversen Dokumenten be schrieben. So wird beispielsweise in US 3 460 523 eine Zusammensetzung beschrie ben, die für die Beschichtung von Öfen nützlich ist und mit der ein möglichst poröser Film, der katalytische Materialien enthält, hergestellt wird. Viele Katalysatormateria lien wurden diesen Zusammensetzungen beigemischt, um die Zerstörung der Fett- und Ölrückstände in der Schicht zu verbessern und damit den Ofen letztlich zu reinigen (US 3 576 667, DE-B 22 11 135, DE-A 26 14 696, DE-A 36 26 424, DE-A 21 17 032).Self-cleaning emails have been known for a long time and can be found in various documents wrote. For example, a composition is described in US 3,460,523 ben, which is useful for the coating of ovens and with the most porous Film containing catalytic materials is made. Lots of catalyst material lien were added to these compositions in order to destroy the fat and improve oil residues in the layer and ultimately the furnace clean (US 3,576,667, DE-B 22 11 135, DE-A 26 14 696, DE-A 36 26 424, DE-A 21 17 032).
Die bisher bekannten selbstreinigenden Emails können jedoch den Selbstreinigungs zyklus gemäß DIN 51 171 nur etwa 5 mal durchlaufen, bevor ihre Eigenschaft der Selbstreinigung verlorengeht. Die Prüfung dient zur Bestimmung der Fähigkeit selbstreinigender Emaillierungen, Fette oder Ölspritzer in tropfenförmiger Form zunächst aufzunehmen und sie dann unter Wärmeeinwirkung größtenteils zu verbrennen. Ein weiterer Nachteil dieser bekannten selbstreinigenden Emails besteht darin, daß die Regenerierung mittels Pyrolyse bei niedrigen Temperaturen nicht möglich ist (US 3 930 062).The previously known self-cleaning enamels can, however, do self-cleaning cycle according to DIN 51 171 only about 5 times before their property of Self-cleaning is lost. The test serves to determine the ability self-cleaning enamels, greases or splashes of oil in a teardrop shape first record and then mostly under heat burn. Another disadvantage of these known self-cleaning emails is in that the regeneration by means of pyrolysis at low temperatures is not is possible (US 3 930 062).
Die bekannten selbstreinigenden Emails können auch nicht im Gegensatz zu anderen Emails durch elektrostatischen Pulverauftrag auf die zu beschichtenden Gegenstände erhalten werden.The well-known self-cleaning emails can not be unlike others Emails by electrostatic powder application to the objects to be coated be preserved.
Aufgabe war es daher, Emailfritten zur Verfügung zu stellen, die es gestatten, selbst reinigende und in ihren Eigenschaften verbesserte Emailschichten herzustellen, und die außerdem durch elektrostatischen Pulverauftrag auf die zu emaillierenden Gegen stände aufgebraucht werden können.The task, therefore, was to provide email frits that would allow us to do it ourselves to produce cleaning and improved properties of enamel layers, and which also by electrostatic powder application on the counter to be enamelled stands can be used up.
Diese Aufgabe konnte durch die erfindungsgemäßen oxidischen Partikelmischungen, die ein Gemisch aus unterschiedlichen Emailfritten, gegebenenfalls mit weiteren Rohstoffen, darstellen, gelöst werden.This object was achieved by the oxidic particle mixtures according to the invention, which is a mixture of different enamel frits, possibly with others Raw materials, represent, be solved.

von selbstreinigenden Emailschichten auf Stahl, die einen elektrischen Widerstand
zwischen 30 × 1013 und 700 × 1013 Ohm.cm, gemessen an der oxidischen Partikel

Vorzugsweise wird direkt anschließend an den Auftrag des Grundemails die erfindungsgemäße oxidische Partikelmischung aufgetragen, ohne daß vorher das Grundemail gebrannt wird (sogenanntes 2-Schicht-1-Brand-Verfahren). It is preferred to send the basic e-mail directly afterwards applied oxidic particle mixture according to the invention without the Basic enamel is burned (so-called 2-layer, 1-fire process).
Die oxidische Partikelmischung hatte folgende Zusammensetzung:
The oxide particle mixture had the following composition:
Die beiden Fritten A und B sowie das Farbmittel FA 1216 der Firma Rhenania (schwarzer Spinell auf Basis Co/Cr/Fe/Mn/Ni) wurden miteinander gemischt und gemahlen. Während der Mahlung wurden 0,3 Gew.-% Silikonöl (Baysilon MH 15 der Bayer AG, Leverkusen) zugesetzt. Die Zusammensetzung wies 30 Gew.-% Fritte A, 70 Gew.-% Fritte B, 2 Gew.-% des Farbmittels und 0,3 Gew.-% Baysilon MH 15 auf.The two frits A and B and the colorant FA 1216 from Rhenania (black spinel based on Co / Cr / Fe / Mn / Ni) were mixed together and ground. 0.3% by weight of silicone oil (Baysilon MH 15 Bayer AG, Leverkusen) added. The composition had 30% by weight frit A, 70% by weight of frit B, 2% by weight of the colorant and 0.3% by weight of Baysilon MH 15 on.
Die Partikelgröße lag unter 100 µm (15 Gew.-% <43 µm). Der elektrische Wider stand des Pulvers betrug 100.1013Ohm.cm. Das Pulver wurde elektrostatisch auf das Grundemail aufgetragen. Anschließend wurde bei 820°C 4 Minuten gebrannt. Die Dicke der selbstreinigenden Emailschicht nach dem Brennvorgang betrug 200 µm.The particle size was less than 100 µm (15% by weight <43 µm). The electrical resistance of the powder was 100.10 13 Ohm.cm. The powder was electrostatically applied to the base enamel. The mixture was then fired at 820 ° C. for 4 minutes. The thickness of the self-cleaning enamel layer after the firing process was 200 µm.
Die Emaillierung wurde gemäß DIN 51 171 getestet. Der Selbstreinigungszyklus konnte mindestens 9 mal durchlaufen werden. Zur Regeneration wurde bei 400°C 2 Stunden lang pyrolisiert. Bei der Emaillierung handelt es sich also um eine sehr gute selbstreinigende Emailschicht, die gegenüber dem Stand der Technik eine erheblich bessere selbstreinigende Wirkung hat. Außerdem kann sie elektrostatisch auf das Grundemail aufgetragen werden.The enamelling was tested according to DIN 51 171. The self-cleaning cycle could be run through at least 9 times. The regeneration was carried out at 400 ° C Pyrolyzed for 2 hours. The enamelling is therefore a very good self-cleaning enamel layer, which compared to the state of the art has a significantly better self-cleaning effect. It can also be electrostatic be applied to the basic email.
